Impact of Maximum PV Penetration on the Voltage Violation in Grid-Connected PV System

The proliferation of distributed energy resources presents both new challenges for low-voltage distribution networks (LVDN). The increase in solar PV integration has raised a number of concerns regarding the potential impacts that could result from high PV penetration, such as voltage violations and fluctuations. Impact studies on PV integration are therefore becoming more and more important in order to comprehend how to advance PV integration efforts without causing a negative impact on the network. Due to the high penetration of distributed PV generators integrated into the distribution grid, reverse power flow can cause significant losses. This work presents a grid-connected PV (GCPV) system loss analysis based on a progressive increase in PV penetration level. To perform the proposed study, the European LV test feeder was used as a test case. A real case study, with data and parameter measurements of a PV generator connected to the Algerian network, is used to validate the simulation methodology.
